Abstract

Fractal theory is usually used to investigate the topography of machined surfaces, but the relationship between fractal dimensions and wear rate is less studied. A contribution in this field is proposed with wear tests performed on the AISI 1046 steel after the grinding by use of the P80, P180 and P320 abrasive sheets. A 3D fractal study of the worn surfaces is carried out by using power spectral density (PSD) in order to examine the relationship between rate of wear and its 3D fractal dimension. The 3D fractal analysis of the worn surfaces showed that higher values of fractal dimensions indicate a larger real contact area and therefore a better wear resistance of the AISI 1046 steel.

三维分形维数与磨料耐磨性的相关性

分形理论通常用于研究加工表面的形貌，但分形维数与磨损率之间的关系研究较少。通过使用P80、P180和P320研磨片对AISI 1046钢进行研磨后的磨损试验，提出了该领域的贡献。利用功率谱密度（PSD）对磨损表面进行了三维分形研究，以检验磨损率与其三维分形维数之间的关系。磨损表面的3D分形分析表明，分形维数越高，表明AISI 1046钢的实际接触面积越大，因此耐磨性越好。
